    keyword=RHRS: All HVs are on now.

    1, First of all, the GUI of 'channels status' somehow is not
    corresponding to the main GUI, so you should check the main GUI slot by
    slot to check all HV channels. 
    
    2, The slot.4(slot#3 slot if starting with '0') contains s2m
    13L,14L,15L,16L, s2m 13R,14R,15R,16R,s0A,s0B, so the last two channels
    are not in used.
    
    3, The last two channels of slot.#14th and the 8th(#7 if start with#0) of
    #15th are not in used. Specially DO NOT turn on channel#7 of #14th
    otherwise all HVs will trip.
    
    4, I don't know why the 5th channel of slot#8 and the 4th chanenl of
    Slot#15th were off. I checked the mean current of slot8.#5 and slot15.#4,
    which are -154.5uA and 0.0uA. The first one is lower than other channels
    is because its HVs is set to be -650, which is -150 lower than others
    (why?). And for the second one, 0 current means this tube or HV must has
    a problem. We can look at the ADC signal later.
